This paper adopted both the numerical and analytical methods to investigate the excavation
stability against base heave failure. The finite element limit analysis method (OPTUM) was …

Seepage induced by the difference of hydraulic head between the ground and the shield's
chamber will adversely affect the stability of tunnel face when tunnels are excavated through …

The horizontally layered or even inclined strata are often encountered in practical shield
tunneling. The influence of inclined strata on face stability of shield tunnels is not fully …

For small radius curve shield tunneling, over excavation is required on the inner side of the
curve to corner the shield machine. Currently, there is no corresponding analytical solution …

Layered soils are becoming increasingly common in tunnel construction. In order to
investigate the stability of horseshoe-shaped tunnel face in layered soils, a rotational partial …

During shield tunneling in sand strata, variations in the state of sand can lead to localized
instability and strength loss, which brings about numerical difficulties. This paper numerically …

Most research into sand liquefaction has predominantly focused on the effects of earthquake
ground motion, with a limited exploration into the possibility of sand liquefaction induced …

The inclined layered stratum is often encountered in the geological and geotechnical
engineering. The stability of the tunnel face in inclined layered stratum plays an important …

The stability of the tunnel face assumes a pivotal significance in tunnel construction safety.
This paper introduces the material point method (MPM) to scrutinize the stability mode and …

The deterioration of groundwater seepage on the tunnel face stability is a principal risk for
tunnelling through watery ground, and a thorough understanding of soil–water coupled …
